A lot of people recommend 5 amps for racing conditions, including the well respected Team Trinity. According to Team Trinity, higher amp charging will result in more acceleration early, but the battery will flatten out towards the end of a race.
"We have been using a linear 6 amp charge rate with very good results. But a 5 amp charge will give you a slightly more runtime." - Fukuyama Racing on GP3300 cells
"Peak detect cut-off ( voltage threshold ): We suggest a .05 ( 50 mv ) for 6 cell packs. We suggest a .03 ( 30 mv ) for 4 cell packs." - Fukuyama Racing on GP3300 cells
"For 3000 NiMH Batteries. Charge at 4 to 5 amps... Discharge at max 20 amps, then your settings will stay the same for cycling, get the battery between 2 to 5 minute break before starting the discharge." - Team Associated
What amp rate should I use to charge my NiCad batteries?
"4A is a bit less punchy, 5A seems to be the best balance between top speed and punch." - Integy on charging 2400 NiCad batteries.

Drill a pin sized hole in the black part of the shock. This will act as an air vent for the bladder at the top of the shock. Basically what happens then is; as the piston moves into the shock air will escape out the pin hole. Add a piece of form at the top of shock to separate the piston from the bleed hole. This separates the oil and the air.
The advantage is the shock will only shock. It will not add to the spring rate.
Associated Spring Work
Well if you modify them. There length is OK, but there diameter is just a little small.
So here is a picture of a Spring diameter adjuster. :-) Squeeze just a little bit and then rotate and do it again until you have 3 or 4 turns on each end big enough to fit over the spring supports of the Shock.
Rear Pivot Blocks/Anti-squat Blocks/Toe Blocks
This is on a mid motor car, so the front is towards us. Note the nut on top of the left one. It has a slotted hole under it. The front aluminum straps between the Pivot blocks is what sets the Toe. Do the math to figure out how much closer together the holes in the strap have to be for the toe you want.Note: the black piece of plastic from the factory pivot block is position under where the front of the transmission will go.Also note the front strap is notched to help the motor mounting plate fit. I made the pivot blocks, but why wouldn't the original parts work. Just cut them a part and elongate the one hole.
If you were to install the transmission without this black piece of plastic you'd distort the transmission case and your car would do some very strange turns as the trans ......
